New plant structure (APAP1) discovery may lead to improved biofuel processing
APAP1 is contrary to prevailing cell wall models that depict separate protein, pectin and hemicellulose polysaccharide networks. The modified sugar composition and increased extractability of pectin and xylan immunoreactive epitopes in APAP1 mutant aerial biomass support a key role for the APAP1 proteoglycan in plant wall architecture and function. The existence of APAP1 in plant walls has significant consequences for understanding of plant wall architecture and function, and potentially for engineering plant cell walls for improved agronomic and renewable biomaterial uses. Pectin, a primary cell wall component, is important in secondary cell wall structure.
